Designer Nate Berkus and husband
Jeremiah Brent on Monday welcomed a baby girl into their family.

Poppy Brent-Berkus was born via
surrogate.

“Jeremiah & I are thrilled to
announce the arrival of our daughter, Poppy Brent-Berkus, born via
surrogate on March 23, 2015,” Berkus wrote in a
Facebook post. “We are so excited to finally be a family of
3.”

“As anyone with a newborn knows, we
have our work cut out for us but couldn't be happier to be embarking
on this life changing journey that is parenthood. Thank you all for
your well wishes and support,” he added.

The men made history in May as the
first gay couple to marry at the iconic New York Public Library,
roughly a year after Berkus proposed atop the 15th-century Inca site
Machu Picchu in Peru.

Berkus, 43, currently hosts the NBC
reality show American Dream Builders, while Brent, 29, is a
designer who appeared on cabler Bravo's The Rachel Zoe Project.
